Specification of Letters Patent.

Patented Oct. 2, 1917.

Application filed November 4, 1912. Serial No. 729,366.

To all whom it may concern:

Be it known that I, Gnonon M. MERWIN,

a citizen of the United States, residing at Berwyn, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Delivery-Pipes for Fodder-Cutters, of which-the following is a specification.

My invention relates to delivery pipes, in general as used in connection with pneumatic mechanism for conveying straw, chafl or other material, such as ensilage, from a machine into a silo or other re'ceptacle,'and in particular to the construction of the de-' livery end of the conveyer pipe whereby it may be adjusted in a manner to deflect the material in a desired direction; the object of my invention being to provide a construction that may be readily manipulated for the required purpose, comprising few parts,

strong and durable and eflicient in operation.

In order that my invention may be clearly and fully disclosed, I have illustrated in the accompanying drawings one embodiment which it may assume in practice, although my invention is not limited to this embodiment and may appear in modified form.

In these drawings:

Figure 1 represents a side elevation of the delivery end of a conveyer pipe having my invention embodied in its construction;

Fig. 2 is a cross section of Fig. 1 along line AB;

Fig. 3 is a plan view of a'bracket sheave mechanism forming part of the pipe adjusting means;

Fig. 4 is a side elevation of Fig. 3;

Fig. 5 represents an end view of part of the bracket member as shown in Figs. 3 and 4.

The samev reference numerals designate like parts throughout the'several views.

1 represents the body of the pipe that may be attached to a fan casing in any of the well known ways, and is provided with a flanged member 2 that is secured to the upper end thereof. 3 represents the delivery end of the pipe, having a flanged member 4: secured to the lower end thereof that isconnected with the flanged member 2 by means of clips 5 in a manner permitting the de livery section to turn about the axis of the body section, and (3 represents a clamping the upper sectionmay be adjusted in a man-' ner to deflect the material in various directions. 1 The curved portions of the deflector and the delivery pipe sections are'open along their inner sides, forming a curved channel along which the material flows under the force of the air blast; the curved ensilage deflecting surface and the member 8 preferably'being disposed in a single arc struck from a common point and of slightly smaller radius than that of the surface of the member 7. It will also be noted that the deflecting surfaceof the member 8 is of such a length as to deflect the ensilage through slightly more than a right angle, the ensilage thereby being directed slightly downward before it passes into the cooperating deflect ing member 7. I

The hinge mechanism 9 includes bracket the delivery pipe,and carrying a sheave 16 that is provided with a threaded axial opening that receives the horizontally disposed end of a rod 17 ,bent upward and laterally at different points intermediate its ends, the opposite end of the rod being secured to the upper ends of the bracket members 10. The sheave member 16 operates as an adjusting nut in controlling the position of the rod 17 and the adjustable section 7 and a rope 18 is received by the sheave in a manner where by the operator may adjust the section 7 from the ground as desired.

In the operation of the device the ensilage is, of course, forced up through the delivery end 3 of the pipe by the blower of the ensilage cutter. As it moves forward it is decontinuation thereof, a sheave carried by sald delivery section and having a threaded fiected outward and slightly downward by the curved deflecting surface of the member 8 in such-a manner as always to be delivered at the proper angle to the adjustable dcflector 7, which then deflects it in such a manner as to spread it within the silo or upon the pile. l/Vhen it is desired to adjust the deflector 7, this is readily acomplished by pulling on the rope 18 in the desired direction, thereby causing the rod 17 to be fed longitudinally of the member 8 in such a manner.as to swing the deflector 7 about its pivot on the slightly down-turned end of the member 8. Y While I have in this application specifically described one embodiment whichmy invention may assume in practice, it is to be understood that the form shown herein is used for purposes of illustration and that the invention may be embodied in other forms without departing from its spirit.

What I claim as invention, and desir to secure by Letters Patent, is: j I

1. In an ensilage delivery mechanism,

a delivery section, an adjustable section hingedly connected thereto and forming a axial opening therein, a rod having a threaded end recelved 1nthe axial opening 1n sa d sheave and its opposite end thereof connected with said adjustable section, and ,means forrotatlng said sheave in opposite directions.

2. In an ensilage dellvery mechanism, a

delivery section curved upward and later ally, an adjustable section hingedly connected therewlth and forming a continuation thereof, a sheave carried on said delivery.

section and having a threaded axially disposed openlng there1n,a rod having a threaded end received in the axial opening in said sheave and its opposite end pivotally connected with said adjustable section, and a rope engaging said sheave whereby it may be, rotated'in opposite directions.

copies of thls alm ma be obtained for 3. In an ensilage delivery mechanism, a

delivery member having an upstanding delivery end, an ensilage deflector fitting the delivery end of said member and pivotally connected thereto, a bracketmember carried on said deliverymember, a sheave carried by said bracket and disposed transversely with respect to said delivery memher, and a threaded member movable longitudinally by said sheave as the latter is rotated, having one end extending through said sheave and the other end pivotally connected to said deflector.

4.In an ensilage delivery mechanism, a delivery member having a curved upper end, an ensilage deflector pivotally connected to the curved end ofsaid delivery member and forming a continuation thereof, a bracket disposed laterally from said delivery memally, an adjustable section hingedly connected therewith, an upstanding bracket member secured to said adjustable section, a bracket member attached to the side of said delivery section, a sheave carried on said last mentioned bracket having a threaded axial opening therein, a rod having a threaded end received in said axialopening and its opposite end pivotally connected to the bracket on said adjustable section, and a rope engaging said sheave whereby it may be rotated in opposite directions.- GEORGE M.
